    2 
    3 DA9063 consists of a large and varied group of sub-devices (I2C Only):
    4 
    5 Device                   Supply Names    Description
    6 ------                   ------------    -----------
    7 da9063-regulator        :               : LDOs & BUCKs
    8 da9063-onkey            :               : On Key
    9 da9063-rtc              :               : Real-Time Clock (DA9063 only)
   10 da9063-watchdog         :               : Watchdog
   11 
   12 ======
   13 
   14 Required properties:
   15 
   16 - compatible : Should be "dlg,da9063" or "dlg,da9063l"
   17 - reg : Specifies the I2C slave address (this defaults to 0x58 but it can be
   18   modified to match the chip's OTP settings).
   19 - interrupts : IRQ line information.
   20 - interrupt-controller
   21 
   22 Sub-nodes:
   23 
   24 - regulators : This node defines the settings for the LDOs and BUCKs.
   25   The DA9063(L) regulators are bound using their names listed below:
   26 
   27     bcore1    : BUCK CORE1
   28     bcore2    : BUCK CORE2
   29     bpro      : BUCK PRO
   30     bmem      : BUCK MEM
   31     bio       : BUCK IO
   32     bperi     : BUCK PERI
   33     ldo1      : LDO_1   (DA9063 only)
   34     ldo2      : LDO_2   (DA9063 only)
   35     ldo3      : LDO_3
   36     ldo4      : LDO_4   (DA9063 only)
   37     ldo5      : LDO_5   (DA9063 only)
   38     ldo6      : LDO_6   (DA9063 only)
   39     ldo7      : LDO_7
   40     ldo8      : LDO_8
   41     ldo9      : LDO_9
   42     ldo10     : LDO_10  (DA9063 only)
   43     ldo11     : LDO_11
   44 
   45   The component follows the standard regulator framework and the bindings
   46   details of individual regulator device can be found in:
   47   Documentation/devicetree/bindings/regulator/regulator.txt
   48 
   49 - rtc : This node defines settings for the Real-Time Clock associated with
   50   the DA9063 only. The RTC is not present in DA9063L. There are currently
   51   no entries in this binding, however compatible = "dlg,da9063-rtc" should
   52   be added if a node is created.
   53 
   54 - onkey : This node defines the OnKey settings for controlling the key
   55   functionality of the device. The node should contain the compatible property
   56   with the value "dlg,da9063-onkey".
   57 
   58   Optional onkey properties:
   59 
   60   - dlg,disable-key-power : Disable power-down using a long key-press. If this
   61     entry exists the OnKey driver will remove support for the KEY_POWER key
   62     press. If this entry does not exist then by default the key-press
   63     triggered power down is enabled and the OnKey will support both KEY_POWER
   64     and KEY_SLEEP.
   65 
   66 - watchdog : This node defines settings for the Watchdog timer associated
   67   with the DA9063 and DA9063L. The node should contain the compatible property
   68   with the value "dlg,da9063-watchdog".
   69 
   70   Optional watchdog properties:
   71   - dlg,use-sw-pm: Add this property to disable the watchdog during suspend.
   72   Only use this option if you can't use the watchdog automatic suspend
   73   function during a suspend (see register CONTROL_B).
   74
